“…Plasmonic scattering efficiency can be tailored by the shape, environment, distribution and size of NPs. An 18% enhancement in PCE for PCDTBT:PC 70 BM-based OPVs has been reported by Jung et al [137] owing to the plasmonic scattering of Ag NPs embedded in the ITO and MoO 3 interface. Au@ Ag core-shell nanocubes were incorporated in OPVs to improve plasmonic scattering as shown in Figure 8F, as reported by Baek et al [110].…”

Lightweight and low-cost organic photovoltaics (OPVs) hold great promise as renewable energy sources. The most critical challenge in developing high-performance OPVs is the incomplete photon absorption due to the low diffusion length of the carrier in organic semiconductors. To date, various attempts have been carried out to improve light absorption in thin photoactive layer based on optical engineering strategies. Nanostructureinduced light harvesting in OPVs offers an attractive solution to realize high-performance OPVs, via the effects of antireflection, plasmonic scattering, surface plasmon polarization, localized surface plasmon resonance and optical cavity. In this review article, we summarize recent advances in nanostructure-induced light harvesting in OPVs and discuss various light-trapping strategies by incorporating nanostructures in OPVs and the fabrication processing of the micro-patterns with high resolution, large area, high yield and low cost.

“…Recently, Choi et al [38] covered Ag NPs with molybdenum oxide (MoO 3 ) under the active layer to study the effect of nanobump assembly (NBA) on the efficiency of plasmonic OPVs. Compared to the flat interfacial layer, this NBA structure showed higher scattering cross-section in tensities and a stronger forward-scattering effect.…”

Light trapping based on the localized surface-plasmon resonance (LSPR) effect of metallic nanostructures is a promising strategy to improve the device performance of organic solar cells (OSCs). We review recent advances in plasmonic-enhanced OPVs with solution-processed metallic nanoparticles (NPs). The different types of metallic NPs (sizes, shapes, and hybrids), incorporation positions, and NPs with tunable resonance wavelengths toward broadband enhancement are systematically summarized to give a guideline for the realization of highly efficient plasmonic photovoltaics. plasmonic effect, organic solar cell, enhanced light absorption

“…Additionally, the series resistance of device with NBA is lower than that of device without NBA. [12] This can be understood by following three reasons. First, the interface between active layer and HEL is enlarged in the device with NBA owing to undulated active layer and protrude HEL layer.…”

We demonstrate novel plasmonic organic solar cells (OSCs) by embedding an easy processible nanobump assembly (NBA) for harnessing more light. The NBA is consisted of precisely size-controlled Ag nanoparticles (NPs) generated by an aerosol process at atmospheric pressure and thermally deposited molybdenum oxide (MoO 3 ) layer which follows the underlying nano structure of NPs. The active layer, spin-casted polymer blend solution, has an undulated structure conformably covering the NBA structure. To find the optimal condition of the NBA structure for enhancing light harvest as well as carrier transfer, we systematically investigate the effect of the size of Ag NPs and the MoO 3 coverage on the device performance. It is observed that the photocurrent of device increases as the size of Ag NP increases owing to enhanced plasmonic and scattering effect. In addition, the increased light absorption is effectively transferred to the photocurrent with small carrier losses, when the Ag NPs are fully covered by the MoO 3 layer. As a result, the NBA structure consisted of 40 nm Ag NPs enclosed by 20 nm MoO 3 layer leads to18% improvement in the power conversion efficiency compared to the device without the NBA structure. Therefore, the NBA plasmonic structure provides a reliable and efficient light harvesting in a broad range of wavelength, which consequently enhances the performance of organic solar cells.
